LEVELING DEVICES FOR TABLES Filed Nov. 15, 1962 United States Patent 3,171,368 LEVELING DEVICES FQR TABLES Melvin Zimmers, New Rochelle, N.Y., assignor to Superior Industries Corp, New York, N.Y., a corporation of New York Filed Nov. 15, 1962, Ser. No. 237,812 3 Claims. (Cl. 108-144) This invention relates to leveling devices for tables, and particularly tables upon which games, such as pool, table tennis or other games are played.

Tables of the character above mentioned should be maintained perfectly level for the proper playing of the game. Such a condition is not always easy to secure because of uneveness in the flooring or other surface upon which the table is rested. It is therefore desirable that some means be provided by which the top of the table, or that part of the table having the playing surface, be adjusted so that such playing surface shall be perfectly horizontal or level.

It is therefore an object of the invention to provide a table top having adjusting means connected to it and by which the top can be raised and lowered at any required points to thereby cause the table top to become leveled and remain so to thereby insure proper play.

More particularly, the invention contemplates the provision of a table top having cross members on its under side, and a vertically threadable rod adjustable through a bracket secured to the table frame, said rod having a laterally-bent end attached to one of the cross members, and by the adjustment of the rod the same is raised or lowered through the bracket to thereby raise or lower the table top accordingly to the required extent to correct any inclination of the table top from horizontal.

With these and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of the invention is disclosed,

FIG. 1 is a sectional view through a table top such as the top of a pool table, table tennis table or other tabie;

FIG. 2 is a front elevational view, with one of the table cross members shown in part and in section, of one of the adjusting or leveling devices; and

FIG. 3 is a side elevation of the leveling device as seen from the left of FIG. 2.

Referring to the drawing, 1 indicates the top of a table of the character herein mentioned, the same being supported in any one of a number of ways, such as by a frame including legs of conventional form. One of the top rails of the frame is shown at 4. Secured to the under side of the table top 1 by means of screws 3, is a plurality of spaced, transversely-extending cross members 2, the same tending to strengthen and reinforce the table top. These cross members are substantially V-shaped in cross section and are composed of sheet metal.

Secured to the inner face of the rail 4 are brackets 5, each of said brackets being located near one of the cross members 2. Each of said brackets is formed with upper and lower flanges indicated respectively at 6 and 7,

3,171,368 Patented Mar. 2, 1965 and the bracket is attached to the face of the rail 4 by means of the screws indicated at 8. Vertically and slidably adjustable through the upper and lower flanges 6 and '7 of the bracket is a threaded rod 9, the same being vertically adjusted through the bracket and maintained in any desired position of adjustment therethrough by means of the nuts 11 and 12 respectively positioned on the rod above and below the bracket.

At its upper end, the rod 9 is bent at right angles to provide the laterally-extending end portion 10 which passes through openings 13 provided in the walls of one of the cross members 2. It will be understood that these adjusting devices are provided at the opposite sides, or ends or elsewhere as required below the table top.

From the foregoing, the operation of the improved leveling device will be readily understood. By the adjustments of the nuts 11 and 12 on the rod 9, the rod will be vertically raised or lowered as required to bring the table to a perfectly level position for proper play. The adjusting or levelling device is so attached to the table that it can be readily removed or replaced, or the table top can be easily detached from it if and when required, and by the adjustment of one or more of these devices the assurance of a perfectly level table top is had.

Having thus described a single embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claim is:

1. A leveling device for table tops of a type having a cross member secured to and extending across its under side, a topsupporting frame including a side-rail located below the table top, a bracket fastened to a face of the rail, a threaded rod slidably adjustable through the bracket, the cross member being apertured, the threaded rod having a laterally-bent end extended through the aperture in the cross member, and nuts on the red above and below the bracket for the vertical adjustment of the rod through the bracket.

2. A leveling device as provided for in claim 1, wherein the bracket is provided with spaced flanges and the threaded rod is slidably adjustable therethrough, and the cross member is a hollow, substantially V-shaped bar.

3. A leveling device for table tops of a type having a table top support above which a table top is mounted, the under side of the table top being provided with a plurality of spaced, hollow cross members, a bracket mounted on the support near each of the cross members, a threaded rod slidably adjustable through each bracket, each rod having an angular end extended through a cross member and parallel to the under side of the table top, and nuts on each rod providing for the adjustment of the same relative to the bracket through which it extends.
